Topic 3: Title: Assessing the risk of quantum computers in detail using a risk assessment framework (Bachelor/Master)
Description: Since quantum computers will be able to decrypt currently used asymmetric cryptography, companies need to take action in order to keep their cryptography safe. One solution to be safe against quantum computer attacks is to migrate to post-quantum cryptography (PQC). But before initiating such a migration, it is essential to conduct a structured risk assessment to evaluate the relevance and urgency of the threat. This thesis aims to systematically identify, analyze, and evaluate the risks associated with quantum computing by applying a recognized information security risk management framework.

Topic 4: Enhancing Event Logs from German State Parliaments via Feature Engineering for Improved Comparative Analysis (Bachelor/Master)
Description: Context plays a crucial role for meaningful process analysis and fair comparisons. To include contextual information in data sets, feature engineering techniques can be used. This thesis focuses on a recently generated data set capturing the executions of processes in German state parliaments. Using feature engineering techniques, the data set will be enhanced with context information. For instance, information about the political parties and their opinions on important topics could be considered (e.g., from the Wahl-O-Mat) and the complexity and controversiality of law proposals could be assessed (e.g., using LLMs). Naively, the idea behind this is that legislative processes may prove to be more feasible and quicker if the political parties have more in common or if a law proposal is less complex or not controversial.

Topic 7: Extending XES and pm4py for Spatial-Aware Process Mining (Bachelor)
Description: With the growing maturity of IoT and sensor technologies, location data is increasingly available in real-world processes and digital twins. As this trend unfolds, the process mining community has also started to recognize the importance of spatial aspects, with emerging research often framed under the terms geo-aware, environment-aware, or location-aware process mining. While the XES standard allows storing location information as simple attributes, this approach can become restrictive for advanced spatial analyses. This thesis proposes an extension of the XES standard to represent location in a more structured way, alongside a pm4py extension for handling heterogeneous coordinate systems to enhance process mining capabilities with spatial awareness.

Topic 8: Uncovering Business Process Structure through Variant Frequencies (Bachelor/Master Thesis)
Description: Business process variants typically follow a Pareto-like distribution: a small number of highly frequent variant accounts for most behavior, while a long tail of variants occurs only rarely [2]. Understanding such variant frequency distributions provides a rich source of insights into the structural characteristics of business processes.
This thesis empirically investigates variant frequency distributions of real-world and simulated processes. It aims to reveal underlying structural patterns and to test different hypotheses regarding their emergence. In doing so, the thesis contributes to our understanding of process structure and may also reveal insights into emergent process behavior.
